Nekotekina c9d8e59dbf PPU LLVM: allow to drop setting SAT flag (optimization, module-wide) 
Implement ppu_attr::has_mfvscr (partially, module-wide search).
If this instruction isn't found, allow to drop setting SAT flag.
It's based on presumption that only MFVSCR can retrieve SAT flag.

Eladash b40ed5bdb7
Patches/PPU: Extend and improve patching capabilities (code allocations, jumps to any address) (#10779) 
* Patches/PPU: Implement dynamic code allocation + Any-Address jump patches

Also fix deallocation path of fixed allocation patches.

Nekotekina 160b131de3 types.hpp: implement smin, smax, amin, amax 
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.

Fix operators == and <=> for synthesized rel-ops.

Nekotekina 0057c89eaa PPU Analyser: follow fallbacks in some cases
